Abstract
The dynamics of reorientation processes of planar oriented nematic liquid crystals can be controlled and improved by 1 kHz continuous, as well as pulsed, auxiliary electric fields. A device and a special software for forming a control signal of complex shape are created. We show that using a four-step control signal for optical switching allows fivefold reduction of switching time compared to conventional two-step signal.
